Measured products
Measured products are gases, vapours and liquids.
Measuring system
Sensor element is the CERTEC® measuring cell with robust ceramic
diaphragm. The process pressure deflects the ceramic diaphragm
and causes a capacitance change in the measuring cell. This capacitance change is converted into an electrical signal and outputted as
measured value via the output signal.
Depending on the process fitting and measurement setup, measured
products can be also viscous or contain abrasive substances.
The CERTEC® measuring cell is available in two sizes:
•
•
ø 17.5 mm with small process fittings and pressure measuring
range 100 bar
ø 28 mm with large process fittings as well as all flange connections
The CERTEC® measuring cell has also an integrated temperature
sensor. The temperature value is outputted through:
•
•
•
Pressure types
The display and adjustment module
The current output
The digital signal output
The measuring cell design depends on the selected pressure type.
Relative pressure: the measuring cell is open to atmosphere. The
ambient pressure is detected in the measuring cell and compensated.
It thus has no influence on the measured value.
Absolute pressure: the measuring cell is evacuated and encapsulated. The ambient pressure is not compensated and does hence
influence the measured value.
Relative pressure, climate-compensated: the measuring cell is
evacuated and encapsulated. The ambient pressure is detected
through a reference sensor in the electronics and compensated. It
thus has no influence on the measured value.
The following presentations show the installation of the CERTEC®
measuring cell into the process fitting and the different seal concepts.

Safety instructions
Voltage supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
•
•
Connect only in the complete absence of line voltage
If overvoltage surges are expected, overvoltage arresters should
be installed
Power supply and current signal are carried on the same two-wire
cable. The operating voltage can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1.
Keep in mind the following additional factors that influence the operating voltage:
•
•
Connection cable
Lower output voltage of the power supply unit under nominal load
(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault
message)
Influence of additional instruments in the circuit (see load values in
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
Use cable with round cross section for instruments with housing and
cable gland. To ensure the seal effect of the cable gland (IP protection
rating), find out which cable outer diameter the cable gland is suitable
for.
•
•
•
5 … 9 mm (0.20 … 0.35 in)
6 … 12 mm (0.24 … 0.47 in)
10 … 14 mm (0.40 … 0.55 in)
Use a cable gland fitting the cable diameter.
We generally recommend the use of screened cable for HART multidrop mode.
Cable gland ½ NPT
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technical data".
If screened cable is required, we recommend connecting the cable
screen on both ends to ground potential. In the sensor, the screen
must be connected directly to the internal ground terminal. The
ground terminal on the outside of the housing must be connected to
the ground potential (low impedance).
With Ex systems it must be ensured that the grounding corresponds
to the installation regulations.

Cable screening and
grounding
5 Connecting to power supply
In electroplating and CCP systems (cathodic corrosion protection) it
must be taken into account that significant potential differences exist.
This can lead to unacceptably high shield currents if the cable shield
is grounded at both ends.
Information:
The metallic parts of the instrument (process fitting, transmitter, concentric tube, etc.) are conductively connected with the inner and outer
ground terminal on the housing. This connection exists either directly
via connecting metallic parts or, in case of instruments with external
electronics, via the screen of the special connection cable.
You can find specifications on the potential connections inside the
instrument in chapter "Technical data".
Connection technology
5.2Connecting
The voltage supply and signal output are connected via the springloaded terminals in the housing.
The connection to the display and adjustment module or to the interface adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Connection procedure
Proceed as follows:
1. Unscrew the housing cover
2. If a display and adjustment module is installed, remove it by turning it slightly to the left.
3. Loosen compression nut of the cable entry
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
45028-EN-131010
5. Insert the cable into the sensor through the cable entry

Fig. 19: Connection steps 5 and 6 - Double chamber housing
6. Insert the wire ends into the terminals according to the wiring plan
Information:
Solid cores as well as flexible cores with wire end sleeves are inserted directly into the terminal openings. In case of flexible cores without
end sleeves, press the terminal from above with a small screwdriver;
the terminal opening is freed. When the screwdriver is released, the
terminal closes again.
You can find further information on the max. wire cross-section under
"Technical data/Electromechanical data"
7. Check the hold of the wires in the terminals by lightly pulling on
them
8. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
9. Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
10. Reinsert the display and adjustment module, if one was installed
11. Screw the housing cover back on
The electrical connection is hence finished.

Setup - Position correction
6 Set up with the display and adjustment module
If with the automatic position correction, the actual measured value
should be taken over as corrective value, then this value must not be
influeces by product covering or a static pressure.
With the manual position correction, the offset value can be determined by the user. Select for this purpose the function "Edit" and
enter the requested value.
Save your settings with [OK] and move with [ESC] and [->] to the
next menu item.
When the position correction was carried out, then the actual measured value is corrected to 0. The corrective value appears with inverse
signs as offset value in the display.
The position correction can be repeated as often as necessary. However, if the sum of the corrective values exceeds 20 % of the nominal
measuring range, then no position correction is possible.
Setup - Adjustment
VEGABAR 82 always measures pressure independently of the process variable selected in the menu item "Application". To output the
selected process variable correctly, an allocation to 0 % and 100 % of
the output signal must be carried out (adjustment).
With the application "Level", the hydrostatic pressure, e.g. with full
and empty vessel, is entered for adjustment. See following example:

If these values are not known, an adjustment with levels of for example 10 % and 90 % is also possible. By means of these settings, the
real filling height is then calculated.
The real product level during this adjustment is not important, because the min./max. adjustment is always carried out without changing the product level. These settings can be made ahead of time
without the instrument having to be installed.
Note:
If the adjustment ranges are exceeded, the entered value will not be
accepted. Editing can be interrupted with [ESC] or corrected to a
value within the adjustment ranges.
For the other process variables such as e.g. process pressure, differential pressure or flow, the adjustment is performed in like manner.

To damp process-dependent measured value fluctuations, set an
integration time of 0 … 999 s in this menu item. The increment is 0.1 s.
Depending on the sensor type, the factory setting is 0.1 s.
Setup - Linearization
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindrical or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed for
these vessels. They represent the correlation between the level percentage and vessel volume. The linearization applies to the measured
value indication and the current output.
Caution:
Note the following, if the respective sensor is used as part of an overfill protection system according to WHG:

9.4 Rectify faults
Reaction when malfunctions occur
The operator of the system is responsible for taking suitable measures to rectify faults.
Procedure for fault rectification
The first measures are:
•
•
•
Evaluation of fault messages, for example via the display and
adjustment module
Checking the output signal
Treatment of measurement errors
Further comprehensive diagnostics options offer a PC with the software PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectified.
Check the 4 … 20 mA
signal
Connect a multimeter in the suitable measuring range according to
the wiring plan. The following table describes possible errors in the
current signal and helps to remove them:

Meaning of the total
deviation
9.5 Calculation of total deviation (according to
DIN 16086)
The total deviation of a pressure transmitter indicates the maximum
measurement error to be expected in practice. It is also called maximum practical deviation or operational error.
According to DIN 16086, the total deviation Ftotal is the sum of the
basic accuracy Fperf and the long-term stability Fstab:
Ftotal= Fperf + Fstab
The basic accuracy Fperf is composed of the deviation FKl and the
thermal change of zero signal and output span FT:
Fperf = √((FT)2 + (FKl)2)
This applies to the digital signal output via HART, Profibus PA or
Foundation Fieldbus. With a 4 … 20 mA output, there is also the
thermal change of the current output Fa:
To provide a better overview, the formula symbols are listed together
below:

You can find the specifications in chapter "Technical data".
Practical example
Pressure measurement in the pipeline 8 bar (800 KPa)
Product temperature up to 50 °C
VEGABAR 82 with measuring range 10 bar, deviation < 0.075 %
Calculation of the turn down: TD = 10 bar/8 bar, TD = 1.25
Calculation - Digital output signal
1. step: Calculation of the basic accuracy
Fperf = √((FT)2 + (FKl)2)
FT = (0.15 %) x (0.5 + 0.5 x TD)
FKl= 0.075 %
Fperf = √((0.15 %) x (0.5 + 0.5 x TD)2 + (0.075 %)2)
Fperf = 0.19 %
Step 2: Calculation of the total deviation
Ftotal = Fperf + Fstab
Fstab = (0.05 % x TD)
Fstab = (0.05 % x 1.25)
Fstab = 0.06 %
Ftotal = 0.19 % + 0.063 % = 0.25 %
Calculation - Analogue
output signal
1. step: Calculation of the basic accuracy
Fperf = √((FT)2 + (FKl)2 + (Fa)2)
FT = (0.15 %) x (0.5 + 0.5 x TD)
FKl= 0.075 %
Fa = 0.15 %
Fperf = √((0.15 %) x (0.5 + 0.5 x TD)2 + (0.075 %)2) + (0.15 %)2)
Fperf = 0.24 %
Step 2: Calculation of the total deviation
Ftotal = Fperf + Fstab
Fstab = (0.05 % x TD)
Fstab = (0.05 % x 1.25)
Fstab = 0.06 %
45028-EN-131010
Ftotal = 0.24 % + 0.06 % = 0.30 %
